API 5L GRB LOJ LOJ HAB COB LOJ LOJ YEEBYog tsim los ntawm high - zoo carbon steel lossis qis {}- teeb duab los ua cov qauv tubular. Nws cov tshuaj muaj kuab lom yuav tsum nruj me ntsis raws li qhov yuav tsum muaj xws liC Tsawg dua lossis sib npaug rau 0.28%, Mn tsawg dua los yog sib npaug rau 1.20%, Nrog tsawg kawg yog cov txiaj ntsig lub zog ntawm241 MPaThiab tensile lub zog nyob nruab nrab ntawm413-517 MPACov. Qhov kev tsim qauv no ua kom muaj zog ua kom muaj zog thaum tswj kev vam meej los ntawm kev tswj cov pa roj carbon ntau (feem ntauTsawg dua los yog sib npaug rau 0.43%).
Gnee pab pawg ua haujlwm tag nrho - cov txheej txheem racts, sizing rauv taws xob, sizing, txias, thiab kev sim ua kom ncaj, thiab kev sim ua kom ncaj. Qhov kub - Rolling cov txheej txheem ua kom tau cov qauv grain, txhim kho cov yeeb nkab qes {}} kub nruj.
Piv rau welded steel kav, tus qauv seamless tshem tawm cov kev ntseeg tsis muaj zog ntawm Welds, muab kev ntseeg siab rau kev ntseeg siab (ib puag ncig ua haujlwm:4-8 MPA) Thiab corrosive media. Siab - zooAPI 5L GRBCov kav dej tseem ua pov thawjSulfide kev nyuaj siab corrosion cracking (sscc) tsis kam, Uas yog qhov tseem ceeb rau kev txhim kho roj.
